Here are some things going on this morning in your world of tech:

Shares of Garmin (GRMN) are up $4.67, or almost 10%, at $51.84, after the maker of GPS systems and portable navigation devices, this morning reportedQ4 revenue of $759.7 million and EPS of 76 cents, beating the average $712.8 million and 62 cents estimate. Revenue growth was highest in the Aviation segment, up 25% at $339 million. CEO Cliff Pemble called the results “strong” in outdoor, fitness and marine as well, and claimed the results as a “solid starting point for 2014.”

For this year, the company projected revenue of $2.6 billion to $2.7 billion, above the average estimate for $2.57 billion, and EPS of $2.50 to $2.60, which is slightly below the average $2.58-per-share estimate.

At the same time, Garmin said its CFO, Kevin Rauckman, will leave the company within a year from now, after deciding to “change the cadence of his professional career” after being at Garmin for 15 years. The company is commencing a search for a replacement.

Apple (AAPL) gained share in the Chinese smartphone market in Q4, according to a piece this morning fromThe Wall Street Journal’s Juro Osawa and Paul Mozur, citing data from research firm IDC that showed Apple had 7% share, up from 6% in Q3. Apple ranked fifth in the market, they note, behind Samsung Electronics (005930KS), Lenovo Group (0992HK), Yulong Computer Telecommunication Scientific, with its “Coolpad” brand, at third place, and Huawei in fourth place.

Shares of Verizon Communications (VZ) are down 7 cents at $45.91, after the company late yesterday said it would issue 1.27 billion shares of common stock to Vodafone (VOD) shareholders to pay for its acquisition of the 45% of Verizon Wireless that Vodafone owned. That is on top of the 2.86 billion shares outstanding for Verizon.

Speaking of wireless, Pacific Crest’s Michael Bowen this morning writes that the nature of U.S. wireless service is changing as more and more carriers move to “early upgrade plans,” where customers pay more on a monthly basis, but don’t have the onerous “early termination fees.”

Writes Bowen, “While subscribers pay higher total monthly amounts under new EUPs (early upgrade plans), wireless pricing transparency will lead to increased service plan pricing pressure over time. Early termination fees (ETFs) are being replaced by device contracts, which reduce churn, but not as effectively as outgoing subsidized plans. We expect pricing competition and increased switching options to elevate churn going forward.”

“Overall, we expect upgrade rates and churn to increase among the carriers,” he concludes.”

Another fellow offering dire words for the wireless market today is Craig Moffett of the semi-eponymous Moffett Nathanson Research, who this morning cites “mounting evidence that we are headed into a price war” between Verizon and AT&T (T) and Sprint (S) and T-Mobile US (TMSU).

“Everyone is being badly hurt by T-Mobile’s aggressive pricing and ETF buy-out promotion, making a serious response (and no, we haven’t seen one yet) more urgent than ever,” writes Moffett.

T-Mobile’s stock is in fact the only one he recommends as a Buy, rating AT&T and Verizon both a Hold, and rating Sprint a Sell.

Jefferies & Co.’s Peter Misek, who follows 3-D printer makers Stratasys (SSYS) and 3D Systems (DDD), this morning writes that “six to 12 major industrial groups are in deep discussions with metal 3D printing companies about major orders that will be integrated into existing production lines,” including General Electric (GE) for so-called LEAP engine.

Based on that, Misek concludes that 3-D printing is “about to burst onto the mass manufacturing floor.”

Shares of 3D Systems are down 10 cents at $77.04 this morning, while shares of Stratasys are up 16 cents at $126.05.

In case you missed it, Drew Fitzgerald and Shalini Ramachandran of The Journal late yesterday wrote that Netflix (NFLX) is contending some service providers, particularly Verizon, are throttling speeds of video downloads to Netflix subscribers, with declines in speed of as much as 14% last month. The authors refer to “plumbing behind parts of the Internet that are invisible to consumers,” a reference to Internet peering points.

In related news, the FCCthis morning said chairman Tom Wheeler intends to take up a challenge by the U.S. Court of Appeals for the District of Columbia to “act to preserve a free and open Internet.”
